Answer:

C. 72 million

Step-by-step explanation:

Put the appropriate value of x into the correct formula and do the arithmetic.

... For the year 2002, x = 2002 -1980 = 22.

Then the population estimate is ...

... h(22) = 51.42 +15.473·log(22)

... = 51.42 +15.473·1.3424

... = 51.42 +20.77

... = 72.19 ≈ 72 . . . . million . . . . . matches choice C.

What are the solutions of the equation (x - 6) (x - 8) =8
enot [183]

Answer:

x=4  x=10

Step-by-step explanation:

(x - 6) (x - 8) =8

We need to multiply out the left side

x^2 -8x -6x+48 = 8

x^2 -14x +48 = 8

Subtract 8 from each side

x^2 -14x +48-8 = 8-8

x^2 -14x+40 =0

We need to factor the left side.  What two numbers multiply to give 40 and add to give -14

-4*-10 = 40

-4+-10 = -14

(x-4) (x-10) =0

Using the zero product property

x-4=0  x-10 =0

x=4  x=10
